Tools/ModelsInteractive, Teaching Resource 2020Interactive Graphic: Interpreting a COVID-19 Test Result
Currently, the most common diagnostic test for COVID-19 relies on reverse transcriptase polymerase chain reaction …
Currently, the most common diagnostic test for COVID-19 relies on reverse transcriptase polymerase chain reaction (RT-PCR), and most often uses samples obtained from the respiratory tract by nasopharyngeal swab. This interactive graphic demonstrates the influence of the prior probability of COVID-19, the test sensitivity (i.e., the probability of a positive test conditional on disease presence), and the test specificity (i.e., the probability of a negative test conditional on disease absence) on the post-test probability of…

ArticlePublication 2019Cost-Effectiveness of Community-Based Childhood Obesity Prevention Interventions in Australia
This study examined the cost-effectiveness of community-based obesity prevention interventions (CBIs) consisting of strategies to …
This study examined the cost-effectiveness of community-based obesity prevention interventions (CBIs) consisting of strategies to promote healthy eating and physical activity for Australian children aged between 5-18 years. A multiple cohort Markov model that simulates diseases associated with overweight and obesity was used to estimate the health benefits, measured as health-adjusted life years (HALYs) and healthcare-related cost offsets from diseases averted due to exposure to the intervention. Health and cost outcomes were estimated over the…

ArticlePublication 2020Translating Population Evidence to Individual Patients
In this paper, the authors describe the differences in population level outcomes compared to individual …
In this paper, the authors describe the differences in population level outcomes compared to individual patients and discuss ways that these are differences. The authors cover topics including the difference between relative and absolute risk and benefit. They use an example of the decision to start anticoagulation in new-onset atrial fibrillation to discuss translating population level evidence to treatment of an individual. These options include generalizability, subgroup analysis, prediction rules, following response to therapy, and even…

ArticlePublication 2020Clinical Decision Making: Using a Diagnostic Test
This article is part of a 6-part series on clinical decision making. The authors use …
This article is part of a 6-part series on clinical decision making. The authors use two clinical examples to review the principles of interpreting diagnostic test results. They outline an approach that can be used to determine how to select and apply tests and their results to the practice of internal medicine. Topics covered in the two case studies include sensitivity and specificity, positive predictive and negative predictive value of tests, and how to estimate…

ArticlePublication 2019Cost-Effectiveness of Clinic, Home, or Ambulatory Blood Pressure Measurement for Hypertension Diagnosis
This study compared three methods of blood pressure (BP) measurement for diagnosing hypertension in primary …
This study compared three methods of blood pressure (BP) measurement for diagnosing hypertension in primary care settings, accounting for the possibility of false-positive (white-coat hypertension) and false-negative (masked hypertension) clinic measurements. Outcomes included quality-adjusted life years (QALYs) and lifetime costs associated with clinic BP measurement, home BP monitoring, and ambulatory blood pressure monitoring (ABPM) under two scenarios: positive and negative initial screening. Data were from published literature, public data sources, and expert input. In the…

ArticlePublication 2017Cost-Effectiveness of Screening for Hypertension and Counseling for Prevention
This article aimed to compare the health and economic impact of 3 services recommended by …
This article aimed to compare the health and economic impact of 3 services recommended by the US Preventive Services Task Force for the primary prevention of cardiovascular disease (CVD): (1) aspirin counseling for the primary prevention of CVD and colorectal cancer, (2) screening and treatment for lipid disorders (usually high cholesterol), and (3) screening and treatment for hypertension. A microsimulation model was used to compare lifetime outcomes from the societal perspective for a US-representative birth…

ArticlePublication 2017Changing the South African National ART Guidelines: The Role of Cost Modelling
This analysis was motivated by the South African Department of Health's request to assess the …
This analysis was motivated by the South African Department of Health's request to assess the cost implications of adopting sets of ART guidelines issued by the World Health Organization between 2010 and 2016.Using data from large South African ART clinics (n = 24,244 patients), projections of patients in need of ART, and cost data from bottom-up cost analyses, the authors constructed a population-level health-state transition model with 6-monthly transitions between health states depending on patients’ age,…

Resource PackPublication, Teaching Resource 2017Resource Pack: CEA Herpes Zoster Vaccine
This resource pack on the cost-effectiveness of herpes zoster vaccination was curated to support Dr. …
This resource pack on the cost-effectiveness of herpes zoster vaccination was curated to support Dr. Lisa Prosser's seminar on November 9, 2017 at the Center for Health Decision Science. Dr. Prosser discussed an economic evaluation of vaccination against herpes zoster. Herpes zoster—more commonly known as shingles—presents a major burden for older Americans but, until recently, the only available vaccine (Zoster Vaccine Live, ZVL) was relatively ineffective past 10 years. A recently approved vaccine–herpes zoster subunit…

ArticlePublication 2016Cost-Effectiveness of Blood Pressure Treatment Guidelines in Adults 35-74
In this article the authors used the CVD Policy Model to compare the cost-effectiveness of …
In this article the authors used the CVD Policy Model to compare the cost-effectiveness of conservative versus intensive blood pressure treatment guidelines in adult hypertensive patients aged 35 to 74 years. Outcomes included in the study were CVD events, treatment costs, quality-adjusted life years, and drug and monitoring costs projected over the years 2016 to 2026. The effectiveness and costs of hypertension were calculated for treatment according to the 2003 Joint National Committee (JNC)-7 or…
